Autochrome

That's an interesting idea, PE, and I believe that we discussed it at one point before. It still needs to be concluded whether or not the particles will be of the right size, thoguh
 
You can get preformed polymeric beads in various micron sizes that are transparent. They can be anionic or cationic and can be used for this.

They are often sold as ion exchange resins, although most of the resins are rather brownish. You have to pick and choose.

PE
 
PE, that's quite interesting. So are you saying that the dyes would be deposited on the resins, or am I misinterpereting you?
 
That's an interesting idea; I'm going to look into this ... just have to find out where to source them.
 
Hey we use cationic resin in our lipsner/smith film cleaning machines and it is a golden/honey color. I could send you a cup full if you like; pm me.
